Mobile Application Suite

Most mobile applications are recombinations of a small number of hard problems — authentication and session handling, media upload, offline behaviour, real-time updates, list performance at scale, and store compliance. Solving those problems well once produces reusable foundations; solving them badly produces the crash rates and one-star reviews that sink otherwise good products.

Each application targets a different intersection of those problems. The book library focuses on search, collections and offline reading with a local cache and sync-on-reconnect. The social application handles profiles, feeds, media upload and interaction at feed scale, with pagination and image pipelines that keep scrolling smooth. The AI assistant handles streaming responses, persisted conversation history and graceful recovery from dropped connections. All three share a common approach to authentication, navigation, state management and release engineering.
